SPECIFICATION forming part of Letters Patent No. 606,304, dated June 28, 1898. Application filed June 7, 1897. Serial No. 639,694. (No model.)

To aZZ whom it may concern.-

Be it known that I, PHILIPP SCHLACHTER, a citizen of theUnited States, residing at Streator, in the county of La Salle, State of Illinois, have invented a new and useful Improvement in Fluid-Press ure Motors, of which the following is a specification.

My invention relates to fluid-pressure motors or engines, and will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which'- Figure 1 is a plan view of my improved motor or engine complete. Fig. 2 is a side elevation of the same with parts in section. Fig. 3 is a vertical transverse section taken in a plane immediately in front of the fly or balance wheel and showing one of the pistoncylinders in section, and Fig. I is a detail plan view.

In the said drawings similar letters designate corresponding parts in all of the several.

views, referring to which- A designates the bed of the motor or engine.

0 O designate standards connected to and rising from the bed.

B designates a support which is connected to and rises from the bed and has a wrist-pin B at its upper end, and C designates a shaft which is journaled in the standards 0'0 and preferably has a longitudinal bore 0 for a purpose presently described. On the forward end of the shaft 0 is keyed or otherwise fixed a fly or balance wheel WV, and on the face of said Wheel is secured, by bolts or other suit. ble means, three (more or less) disks D. These disks D have central circular apertures a, and they also have the walls of said apertures rabbeted at their inner sides, as indicated by I], (see Fig. 2,) so as to enable them to receive the circular bases 0 of the piston-cylinders D and secure said cylinders and their valve-chests to the face of the wheel in such a manner as to permit of free oscilla cylinders to the face of the Wheel and at the same time promoting the free oscillation of the cylinders.

As shown in Fig. 2, the cylinders D are each provided with an ordinary valve-chest d, ports 6 for the admission and exhaust of the fluid-pressure, a chamber f, connected by a port (not shown) with the atmosphere, and a balance slide-valve g for controlling communication between the interior of the valvechest and the ports 6 and communication between said ports 6 and the exhaust-port in the usual manner. The valves g have stems h, which are connected by pitmen i to a wristpin E on a support E rising from the wristpin B, the said wrist pin E being so arranged, as illustrated, that the valves will be operated to move the pistons D of the several cylinders, which are connected to the wristpin B by rods D in the proper direction, according to the positions of such cylinders with respect to the pin B.

The valve-chests d are supplied with fluidpressure from the hollow shaft 0 through pipes I I as better shown in Fig. 2. The pipes I are preferably of metal, and, communicating with the interior of the hollow shaft at 1, they extend radially and thence transversely through the wheel and disks D, as shown. The pipes I connect the upper ends of the pipes I and the valve-chests d, and they are formed of rubber or other flexible material suitable to the purpose, so as to pre vent them from interfering with the free oscillation of the cylinders upon their center of fixture.

It will be appreciated from the foregoing that when fluid-pressure is let into the valvechests from the hollow shaft 0 and its passage into the piston-cylinders is automatically controlled by the slide-valves in the manner before described the pistons will push against or pull on the wrist-pin B, according to theirposition with respect to the same, and will thereby continuously rotate the balance wheel and shaft. It will also be appreciated that the piston-cylinders and their appurtenances will materially add to themomentum of the wheel, and thereby adapt the same to be run with much less power than would otherwise be the case. With all of this it will be observed that the construction as thus far described is very simple and compact and at the same time is durable and well calculated to Withstand the usage to which engines are ordinarily subjected.

G designates a reservoir for compressed air, which is the fluid-pressure preferably employed.

H designates a pipe which is connected at one end to the reservoir and at its opposite end by a suitable swivel connection H with the rear end of the shaft 0, and F F are aircompressors or air-compressing pumps, which may be of the ordinary or any suitable eonstruction and are suitably connected with the interior of the reservoir. ors are arranged below the shaft 0, and they have their piston-rods terminating at their, upper ends in straps F F, which receive eccentrics K on the shaft 0, whereby it will be observed that when the shaft 0 is rotated the pistons of the compressors will be reciprocated and air will be compressed in the reservoir G.

In the practical operation of my improved motor or engine about one hundred pounds of compressed air is stored in the reservoir G by some extraneous means prior to starting the engine, and when the engine is to be started a throttle-valve (not shown) is opened,

so as to establish communication between the reservoir and the balance-shaft C. This compressed air acting against the pistons D will rotate the balance or fly wheel W and the shaft 0, and through the medium of the latter will reciprocate the pistons of the aircompressors F F and compress air in the reservoir G and replenish the same. This is due to the fact that when the Wheel Wis rotated at a high rate of speed the engine, in virtue of the momentum afforded by the piston-cylinders being arranged on the wheel at a distance from the center thereof, is enabled to overcome the pressure in the reservoir and force air therein.

When desirable, the air-compressors and their appurtenances, together with the reservoir G, may be dispensed with, and the pipe The said compress- I-I maybe connected with any suitable source of fluid-pressure supply.

Having thus described my invention, what I claim is 1. In a fluid-pressure engine, the combinanected to the face of the fly-wheel and having circular apertures and also having the walls of said apertures rabbeted at their inner sides, yokes connected to said disks, piston-cylinders arranged within said yokes and having trunnions journaled therein and also having valve-chests and heads journaled in the rabbets of the disks so as to enable the cylinders to oscillate on their centers of fixture, pistons in said cylinders connected with the wrist-pin B, slide-valves in the Valvechests connected with the wrist-pin E, pipes connected to and extending radially from the hollow shaft and transversely through the flywheel, and flexible connections between said pipes and the valve-chests, substantially as specified.

2. In an engine of the type described, the combination of a flywheel,suitably-supported wrist-pins, a disk secured to the face of said fly-wheel and havinga circular aperture and also having the wall of said aperture rabbeted at its inner side, a yoke connected to the disk, a piston-cylinder arranged in the yoke and having a trunnion journaled therein and also having a valve-chest and a head journaled in the rabbet of the disk, a piston in said cylinder connected with one wrist-pin, and a valve in the chest connected with the other wrist-pin substantially as specified.

In witness whereof I have hereunto subscribed my name, on this 25th day of May, 1897, in the presence of two subscribing witnesses.

PHILIPP SCHLAGHTER.
